267e Uncertainty Source / Dual Filter

The Model 267e combines a noise source, a random voltage source, and a simple two channel filter. Noise comes in three flavors. White noise is electrically flat, but acoustically balanced toward the high end of the spectrum (+3 db/octave).

227e System Interface

The Model 227e System Interface facilitates the equalization, spatialization, mixing, and routing of audio signals in four-channel studio or performance environments. There are a total of nine signal inputs. Four are primary inputs, and can be individually located in two-dimensional space under…

297 Infinite Phase Shifter

The Model 297 Infinite Phase Shifter displaces the phase of an applied signal by up to 1,800 degrees, depending on frequency and number of stages selected. The phase-shifted signal may be combined with the original to create a moderately warped comb filter with complementary outputs. Notch density.

259e Twisted Waveform Generator

The 259e Twisted Waveform Generator is nearly identical to the original 259, including the implementation of the original digital waveshaping, aliasing noise, and foldover frequencies. The new version, however, adds self-modifying, screeching, snarling responses that reflect weird internal…

251e Quad Sequential Voltage Source

Four 50 stage sequencers, each with programmable pulse and control voltage outputs. A separate editing section permits setting each parameter for a selected sequence can be edited while running and follow the edit stage when stopped.

285e Frequency Shifter / Balanced Modulator

The top section of the dual-function 285e performs frequency shifting; up and down outputs are simultaneously available. The reference frequency can be externally applied or internally generated; the latter can be voltage-controlled and modulated using FM.
